Activities of PEPC and PEPCK (μmol CO2 g–1fw h–1) extracted from young fully developed leaves of Aechmea ‘Maya’ in the middle of the night (PEPC) and midday (PEPCK) under control light-dark cycle (LD, white light, 100 μmol m–2s–1), continuous dark (DD) and different monochromatic light-dark cycles (10 μmol m–2s–1)
Data are means±SE (n=3) and those in each column followed by a different letter are significantly different by Tukey’s Studentized range test (P< 0.05).
